As part of its financial announcements today Take Two has confirmed that its new 2K Marin studio is developing a sequel to BioShock.
BioShock 2 is due for release towards the end of 2009.
2K Marin was founded by a number of former members of the 2K Boston team which developed the original BioShock. The original game has sold over two million units worldwide.
Located in Novato, California, the new studio was originally announced as a hub for developing new IP, as well as co-developing products with other 2K studios around the world.
"We're focused on continuing to bring new brands and cutting-edge gameplay to market with the creation of the 2K Marin studio. 2K Marin will build upon our success in creating and leveraging triple-A franchises," Christoph Hartmann, president of 2K, commented at the time.
